style="font-size:16px;color:#E53333;"><strong> 1、信號傳送距離</strong></span> </p> <p> <span style="font-size:16px;">就地顯示壓力可以選用數(shù)顯式壓力表、液柱式壓力表、浮標式壓力表等；需要遠傳壓力信號或?qū)毫π盘栠M行控制時，可以選擇遠傳壓力表、控制式壓力表、報警式壓力表等。</span> </p> <p> <span style="font-size:16px;"> <strong><span style="color:#E53333;"> 2、測點個數(shù)</span></strong><span style="color:#E53333;"><strong></strong></span></span> </p> <p> <span style="font-size:16px;">需要同時測量多點壓力時可以選擇壓力巡檢儀表。</span> </p> <p> <span style="font-size:16px;"> <strong><span style="color:#E53333;"> 3、量程</span></strong><span style="color:#E53333;"><strong></strong></span></span> </p> <p> <span style="font-size:16px;"> 根據(jù)被測壓力大小選擇合適的壓力表量程。穩(wěn)定壓力，被測壓力應落在1/3~2/3量程之間；脈動壓力，**z大壓力應不超過滿量程的1/2；高壓，**z大壓力應不超過滿量程的3/5。</span> </p> <p> <span style="font-size:16px;"> <strong><span style="color:#E53333;">4、精度</span></strong></span> </p> <p> <span style="font-size:16px;"> 根據(jù)生產(chǎn)過程允許的**z大測量誤差選擇，兼顧經(jīng)濟性、可靠性與耐用性。</span> </p> <p> <span style="font-size:16px;"> <strong><span style="color:#E53333;"> 5、外形尺寸</span></strong><span style="color:#E53333;"><strong></strong></span></span> </p> <p> <span style="font-size:16px;">數(shù)顯壓力表一般選擇表盤直徑為φ60mm、φ80mm、φ100mm；指針儀表表盤直徑一般選為φ150mm，較差照明條件下可增大到φ200~φ250mm。</span> </p> <p> <span style="font-size:16px;color:#E53333;"><strong>6、被測介質(zhì)特性</strong></span> </p> <p> <span style="font-size:16px;"> 黏稠、易結(jié)晶、具有腐蝕性或含固體顆粒的被測介質(zhì)應選用平膜壓力表或帶化學密封裝置的壓力表；蒸汽或高溫介質(zhì)應選不銹鋼壓力表或安裝冷凝圈；測特殊化工介質(zhì)要選用**壓力表，如含氨介質(zhì)選氨用壓力表，含硫介質(zhì)選抗硫壓力表等。</span> </p><h1> <span style="font-size:18px;">壓力控制器工作原理</span> </h1> <p> <span style="font-size:18px;">控制器產(chǎn)品在制造生產(chǎn)時每種產(chǎn)品都有其特定的工作壓力范圍（量程），在此范圍內(nèi)客戶可預先設定好需要開關工作的壓力值，此值也稱壓力開關的設定點。在接入系統(tǒng)后，當被測介質(zhì)的壓力大于（小于）設定點時傳感器產(chǎn)生階越信號，觸發(fā)控制器內(nèi)部的微動開關，使系統(tǒng)回路打開（閉合）?？刂破魍ǔＥ渲靡粋€SPDT型微動開關，每一個SPDT開關均可設定為常閉或常開狀態(tài)，設為常開狀態(tài)時，當微動開關動作則使系統(tǒng)回路閉合。常閉狀態(tài)是使系統(tǒng)回路斷開。</span>
